Absolute contraindication for endovenous abalation in varicose veins
High-Yield Explanation
An acute occlusive DVT is an absolute contraindication to endovenous thermal ablation, whereas a chronically recanalized deep venous system in the extremity to be treated is a relative contraindication. Care must be taken to ensure that superficial venous ablation will not compromise the venous outflow of the post-thrombotic limb.Ref: Sabiston 20e pg: 1866
